guide to determine from which vines the melons came. It 
could not be said that the infection came from the seed, for 
these vines were no worse infected with the blight than 
other melons on the station property or in the adjacent 
country. Some of the seed was held over for planting in 
1900 , and the results are like those mentioned. 
All of the fields in the vicinity of Rocky Ford were 
more or less affected with the disease, the spread being 
much more rapid than anyone anticipated. This caused us 
to inaugurate experimental work, late in the season, for its 
control. 
There were, at the station, seven rows of cantaloupes, 
each 275 feet long, on alfalfa sod. One of these was sprayed 
with the Bordeaux mixture July 31 , and again August 11 . 
Th is work confirmed the results enumerated above. 
Another row was sprayed with the ammoniacal copper 
carbonate solution (1 oz. to 6 gallons of water) August 4 , 
and again August 8 and 11 . Some benefit was secured 
from this spray, in the same way it was with the Bordeaux 
mixture, but it was not so pronounced, nor does the spray 
adhere so well to the plant. 
Mr. I. D. Hale had some June planted melons which we 
secured for experimental purposes. They were sprayed 
with the Bordeaux mixture July 27 , and again July 31 and 
August 11 . 
About one-eighth of an acre of melons was sprayed for 
G. W. Swink, August 15 and 16 . Owing to press of work 
only one application was given these vines, but the benefit 
from the spray was quite marked when compared with the 
remainder of of the field. 
August 21 we sprayed about one acre of late melons at 
I. D. Hale’s, in which the blight was very bad; it appeared 
as though no returns could be secured from the field. 
Even after the vines were thus affected there was a marked 
improvement in the appearance of the vines, and the fruit 
did not deteriorate in quality nearly so rapidly as in an 
unsprayed portion of the field. 
Mr. C. S. Fenlason had about \Yi acres of late melons 
which were secured to spray, to verity previous results apd 
to further study the cost of the work. Y he vines were very 
large, completely covering the ground. 
A barrel of spray mixture was put in a slip scraper 
which was pulled backwards, and two rows taken on 
each side. The work was done August 22 and 23 . 
Twenty-two pounds of copper sulphate were used to make
